What should be paid attention to in crab culture? What does it eat?

There are three kinds of bait that should not be fed with skin. Feeding with skin not only has low feed conversion rate, but also has high fat content in skin. After feeding a large number of skins, it is easy to form an oil film on the water surface, which is easy to cause hypoxia in the water body and affect the growth of crabs. Potatoes Crabs don't like to eat, and after feeding, they sink to the bottom of the pool to rot and deteriorate, which is easy to cause water quality deterioration and induce crab disease.

Sea fish. First of all, long-term freezing of marine fish leads to a large number of pathogens, and long-term feeding is easy to lead to high morbidity and mortality of river crabs. Secondly, the salt content of marine fish is high, and the gonad development of river crabs is accelerated after feeding. River crabs are omnivores, and they can eat almost all kinds of food. Wild crabs mainly feed on aquatic plants and decaying plants, and occasionally eat some small fish, shrimps, snails, worms and so on. It is best to raise crabs mainly with artificial feed, and occasionally feed prawns, corn, soybeans and other foods.

You must choose large containers to raise river crabs, otherwise they will eat people. River crabs are omnivores and can eat anything. Generally, wild river crabs mainly feed on aquatic plants and decaying plants, and occasionally they can eat some small fish, shrimps, snails, worms and sometimes even sediment. The artificially raised river crabs can be fed with food such as egg yolk and internal organs. When raising crabs at home, you can give crabs, fish and shrimp, snails, egg yolks and other foods, but you should pay attention to controlling the feeding amount to about 6% of the crab's weight to avoid water pollution caused by excessive feeding. First of all, animal feed is also essential for river crabs. Because there are many kinds of animal feed, which contains rich nutrients, it can promote its rapid growth.
